Cardiac pacemaking in the sinoatrial node

Physiological Reviews, 1993
Major topics addressed in this review on cardiac pacemaking in the sinoatrial node are; 1) isolated pacemaker cells; 2) membrane currents of sinoatrial node cells; 3) mechanism of pacemaking; 4) regulation of pacemaker ...

The surgical anatomy of the sinoatrial node

Surgical and Radiologic Anatomy, 1991
The sinoatrial nodes (SAN) were observed, dissected, and measured on 95 adults and 30 child hearts under a dissection microscope. The majority of the SANs in adults are characterized by their pale color, firm consistency, and the location in relation to the penetration of the SAN artery, and they can be located in the superior part of the terminal ...

Connexins in the Sinoatrial and Atrioventricular Nodes

2006
The sinoatrial node (SAN) and the atrioventricular node (AVN) are specialized tissues in the heart: the SAN is specialized for pacemaking (it is the pacemaker of the heart), whereas the AVN is specialized for slow conduction of the action potential (to introduce a delay between atrial and ventricular activation during the cardiac cycle).

Reconstruction of the human sinoatrial node

The Anatomical Record, 1967
AbstractThe superior vena cava and adjacent right atrium containing the sinoatrial node in each of five human hearts was studied histologically in serial section. The tissue block of a 41 year old man was reconstructed in four colors to provide a three‐dimensional model of the sinoatrial node, atrial relations, blood supply and nodal configuration. The

The mammalian sinoatrial node

Cardiovascular Drugs and Therapy, 1988
The sinoatrial node (SAN) was discovered in 1906 by Keith and Flack. The relation between its ultrastructure and function was first studied by Trautwein and Uchizono in 1963, whereas this relation was definitely established by Taylor and coworkers in 1978. The impulse originates from cells with a relatively low percentage of myofilaments.

Functional morphology of the pig sinoatrial node

Journal of Molecular and Cellular Cardiology, 1987
The porcine sinoatrial node in an isolated right atrium preparation is characterized by unifocal impulse generation. It has a rather elongated shape and the larger part of its volume is taken up by collagen and fibroblasts. The impulse appears to emerge from a site where the percentage of myofilaments is relatively low. The impulse is propagated faster

Disturbances of Sinoatrial Node Function [PDF]

open access: possible, 2000
The spectrum of human cardiac performance is amazingly broad with cardiac output varying 10–20-fold between that measured during the deepest of sleep to that seen at peak of exercise. In large part this tremendous cardiac reserve is modulated both by cardiac contractility as well as the heart rate itself.
